Wireline Origins & the Wire
1912: Conrad Schlumberger conceives the idea for electrical measurements
1927: First electrical downhole log in Pechelbronn, France1930’s: Introduction of ‘Round’ Slickline
Hand powered - wells were shallow
Measuring device hand held against the wire
Line Tension – felt by operators leather covered hand on the wire
Mechanically driven reels

Slickline Intervention and Diagnostics
Benefits
small footprint, mechanical integrity, logistical simplicity,
operational efficiency, cost effectiveness
Limitations
clarity of toolstring status
depth precision
downhole tool capability
over dependence on slickline operator’s experience level
. . . maintain the benefits, overcome the limitations

Digital Slickline Case Study – Optimized Intervention Saves Time
Requirement – Well Prep and Production Logging
slickline: gauge cutter, plug installation, SSSV
lockout
eLine: static gradient, drawdown/shut-in
pressure/temperature survey per zone
Application – Digital Slickline used for entire operation
single unit / crew mobilization
single rig up / down operation
pressure control equipment rationalization
Result
risk minimization / elimination
reduction in operational time and deferred production

Digital Slickline Case Study – Non explosive setting
Accurate depth setting of 2.75” bridge plugs in 3.5” tubing
Six plugs set at depths ranging from 4,100 ft to 12,699 ft
Application: Digital Slickline LIVE Set
Six Plugs set without explosives using digital electro-hydraulic setting tool
Real time accurate setting depth achieved using real-time GR and CCL correlation
Plug setting QC provided through real time downhole tool status monitoring on surface

Wireline Efficiency Gaps – A Brief Summary
Torque/ Bird Caging/ Stranded armors
Gas Migration/ High Pressure Sealing
Excessive friction in deep wells
Limited running Speeds
Grease Injection & spillage
Large WHE and grease tubes
Limitations in Subsea Intervention
“Kinked “electric line
Bird-Nested electric line
Polymer encapsulated logging cable
Smooth jacketed outer profile
Compact Dual Packoff
New Generation Wireline
Improvements of Polymer Filled Wireline Cables
Creates a seasoned cable:• Faster running speed
• Time and risk reduction
Better sealing on high pressure wells:• Minimizes the use of grease for sealing
• Allows for faster running speeds
• Reduces risk of hydrocarbon release
Minimizes torque in the cable:• Allows for more runs between cable servicing
• Standard alloy cable requires servicing every 1-3 jobs
• Reduces incidents due to bird-caging / torque etc.
Eliminates gas migration:
• Between the core and inner armor wires
• Between inner and outer armor wire
Conventional Polymer Filled
Polymer Coated
Polymer Filled Wireline – Efficiency Gains
Torque/ Bird Caging/ Stranded armors
Gas Migration/ High Pressure Sealing
Excessive friction in deep wells
Limited running Speeds
Grease Injection & spillage
Large WHE and grease tubes
Limitations in Subsea Intervention
√ Torque Balanced Armor package
√ Sealable polymer filled cable
√ Friction reduced by 40%
√ Limited only by safe winch policy
√ Unique Well Control (no grease)
√ Compact “EziSeal” packoff
√ Enables deepwater intervention
Advanced Wireline Benefits
Faster RIH/POOH, Faster Rig Up
Encapsulated armors
No grease
Less friction
GRE (Glass-Reinforced-Epoxy) Lined tubing protection is applicable
Efficiency
Lower Risks
Reach the “Unreachable ” reservoir information
Environmentally Friendly
